摘要：
The main propositions of Rabotnov's two-layer model of a shell are given. It is shown that the Rabotnov's functional can be obtained from the mixed variational principle of creep theory. The notion of critical time is introduced and a procedure for obtaining an explicit formula for it using a variational equation is described.
